Secure Edit Controls

KeePass supports security-enhanced edit controls.

KeePass was one of the first password managers featuring secure edit controls. The
edit controls used in KeePass are resistant to password revealers and password
control spies. Additionally, the entered passwords are protected against
memory dumping attacks: the passwords aren't even visible in the process memory space
of KeePass!

KeePass uses secure edit controls only when the hiding behind asterisks option
is turned on! If you show the passwords in plaintext, they won't be protected
(secure edit controls are just disabled then, replaced by standard Windows edit
controls).

Selection limitation:
A limitation of these secure edit controls is that you can't select
a range of characters. You for example cannot select 3 characters and replace
them by the current contents of the clipboard using the paste command.

If you want to delete all the contents of a secure edit control, press
Shift+Home or
Shift+End.
This will remove all entered characters.
